+
+=item C<child_type>
+
+Returns the C<item_type> for children of C<$self>.

+=item C<children_sorted>
+
+Returns an array reference of direct children (not of grandchildren)
+for C<$self> ordered by their positional column in ascending order.
+
+=item C<section>
+
+Returns the section this item belongs to. It can be C<$self> if
+C<$self> is already a section, its parent or grandparent.
